Glue That Only Hardens When Voltage Is Applied

It seems like using this type of glue underwater or in the human body would be a bit difficult considering it hardens when voltage is applied. eek!

A team from Singapore's Nanyang Technological University is coming at it from a slightly different angle by developing a glue that hardens when an electrical charge is applied. As the team's lead scientist Professor Terry Steele points out, most glues don't work when they're wet, in the same way that sticky tape won't stick to a wet surface because the adhesive will stick to the water rather than the surface. Steele and his team have been at work for more than a year, crafting a new form of adhesive that can perform its job in wet conditions, such as underwater or in the human body.
